I used the free version for a while. Now I want to switch to the paid version. I looked at purchasing from the website, there are “Premium” and “Ultimate” options and sub-options of these options as 1 pc and 10 pc. The prices are reasonable, but there is no “Ultimate” option in the upgrade offers given in the Windows application, although the prices are much more reasonable. Some features are offered a la carte. This is actually better for me, I can buy “Premium” and only choose the features that are useful to me. There is no problem on the web, everything is clear, there are 1 and 10 user options. However, since it is not clearly stated in the application, I assume the offer is for 1 pc, not 10 pc. I do not want this, I wish there was a reasonable offer in the application for 10 pc. Can I upgrade to “Ultimate” and 10 pc options after upgrading to “Premium” from the application?
